Its 151 × 65 × 102 mm make it the exact replacement for the 7 Ah battery fitted as standard to many power wheelchairs and mobility scooters. - Approved for air and sea transport (VRLA). - No maintenance, no water top-ups. - Sealed AGM/GEL: safe indoors and in transport. - AGM: faster recharging and better cycle resistance than a conventional battery. ### What the Kronobat ES7-12 is for The Kronobat ES7-12 is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.39 kg and F1 / F2 terminals. ### Dimensions, polarity and mounting In terms of format, the Kronobat ES7-12 measures 151 × 65 × 102 mm (length × width × height) and weighs 2.39 kg. It uses F1 / F2 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### The Kronobat ES7-12: AGM Deep Cycle range and AGM technology The ES7-12 is part of the Kronobat **AGM Deep Cycle** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### Why choose Kronobat batteries Kronobat is the exclusive brand of baterias.com: batteries made to the same production standards as the leading brands, with a value for money that is hard to match and an official warranty. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Warranty and coverage The Kronobat ES7-12 comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you. ### Usage and maintenance tips Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. ### Shipping, delivery and returns Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the ES7-12 model AGM? What does this technology offer? Yes. The ES7-12 from Kronobat uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How is the Kronobat ES7-12 battery installed in the vehicle? In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What is the service life of the ES7-12 model? Expected lifespan of the Kronobat ES7-12 is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the measurements of the ES7-12 model? Dimensions (length × width × height) are 151×65×102 mm — also written as 151x65x102 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### What are the equivalents of the ES7-12 model? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level. ## Equivalent batteries - [MK POWERED ES7-12SA](https://baterias.com/gb/battery-mk-es7-12sa-12v-7ah) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-03*
